Disable shortcut toolbar in subform (A2K - SR1)

Whenever I edit a record in a subform's datasheet, the right-click shortcut popup is enabled and an annoying editing toolbar is displayed below my main menu and toolbar. I can disable the shortcutmenu by turning it off like
Me.Subform.ShortcutMenu = False
But I can't disable the display of the toolbar. I tried to redirect the shortcut menubar to my default like
Me.Subform.ShortcutMenubar = "MyDefaultToolbar"
without success.
